Does a machine-learning algorithm accurately classify ECG waveforms for the presence of Brugada Syndrome without the use of sodium channel blockers?
A novel machine-learning algorithm can accurately detect Brugada Syndrome from standard ECGs, potentially eliminating the need for risky sodium channel blocker provocation tests.
Estimación del efecto: AUC 0.934
One in 10 cases of sudden cardiac death strikes without warning as the result of an inherited arrhythmic cardiomyopathy, such as Brugada Syndrome (BrS). Normal physiological variations often obscure visible signs of this and related life-threatening channelopathies in conventional electrocardiograms (ECGs). Sodium channel blockers can reveal previously hidden diagnostic ECG features, however, their use carries the risk of life-threatening proarrhythmic side effects. The absence of a nonintrusive test places a grossly underestimated fraction of the population at risk of SCD. Here, we present a machine-learning algorithm that extracts, aligns, and classifies ECG waveforms for the presence of BrS. This protocol, which succeeds without the use of a sodium channel blocker (88.4% accuracy, 0.934 AUC in validation), can aid clinicians in identifying the presence of this potentially life-threatening heart disease.
Melo et al. (Fri,) conducted a observational in Brugada Syndrome. Machine-learning algorithm was evaluated on Classification of ECG waveforms for the presence of Brugada syndrome (AUC 0.934). A machine-learning algorithm successfully classified ECG waveforms for the presence of Brugada syndrome without sodium channel blockers, achieving 88.4% accuracy and an AUC of 0.934 in validation.
